Impedance mis-match?

I would use 75 ohm cable, since reflection from the other end is possibly worse, as Al stated, but also because output RCA connector is not likely 75 ohm anyway.

I would use very short cable - as short as possible. Wire becomes transmission line when propagation time is longer than 1/8 of transition time. Assuming typical 25ns output transitions cable should be limited to propagation time of about 3ns, equivalent to about 2 feet (5ns/m). Since internal connections on both sides (including PCB traces) count I would limit it further to 1foot max. Otherwise I would use 1.5-2 m cable to ensure that reflections from the other end miss originating transition.

I use a V-link192 connected with a 75 ohm Wireworld Starlite 7 cable into a Wyred4Sound Dac1. Sounds better than my Esoteric UX-3 SACD player.

I'm using a v-link to a bifrost and have so for almost a year. It gets used about 40 hours a week. Never has faltered at all and sounds spectacular for the money.

I've been using a V-Link 192 to a Schiit Gungnir via DH Labs Silver Sonic D-750 for a year. Things sound great.

Here's the response from MF...

most digital parts I know of are 50 ohms (or 100 ohms balanced) to preserve square wave edges. That said at these relatively lowish frequencies (low MHz) such a mismatch is unlikely to cause problems unless going into extremely long cables.
So nothing for your average home user to worry about.....

I am extremely happy with mine - my Bifrost has never sounded so good.

And remember - Don't shoot the messenger :-)
